It started with a glitch with the radio/navigation system flashing back and forth and not working. The cooling fan on the vehicle would run for about 10 minutes. The blind spot warning would blink on and off and there was no one else on the road. Then two days later the check engine light came on for about 5 days. Then three days later there was a loss of battery power and the indication light came on stating the car was in battery save mode. Then two days later the power steering system was lost on the highway and all the warning lights on the dash were flashing. The car stalled and refused to start.

Chevy transmissions for the following years of 2015-2019 have has extensive problems. They include hard shifting, break down, and full blown blowing up on consumers. This has cause consumers to fork out on average $6000 to have a transmission replacement. There is over 2000 people on reddit who have reported this issue and chevy/gm has not opened a recall due to the [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The transmission started shifting hard in second gear and also whines at higher RPMs. The code it’s throwing is a Torque Converter Clutch issue. We were put in danger because it almost stalled on the highway. It has been inspected by a mechanic. There were no warnings prior to the failure.

Braking is diminished when vehicle is moving at slow speed and brake pedal is pressed. The vehicle brake assist engages by pulsing, increasing the braking distance by not stopping the vehicle no matter how hard the brake pedal is pushed. Emergency brake is used to prevent vehicle from colliding. This may be related to NHTSA 19V645

I purchased my vehicle after the recall 19V-645 regarding the brake pump was issued. My vehicle was a part of that safety recall, and the module was reprogrammed in September 2019 (N192268490-01). The pump has not been previously replaced according to service records. I purchased my vehicle from a dealership in April 2021. I recently (late 2023) started having issues with my brakes, having increased brake pedal effort, a hard brake pedal, and increased stopping distance. I have had the brake assist alert come on several times. The issue happens more frequently at lower speeds. My park assist alert also comes on regularly when applying the brakes. I have taken my vehicle to GM several times regarding the park assist issues, but they have only cleared the computer codes and cannot figure out why they keep coming back, as there is no detectable issues with the system. I have also brought my vehicle in due to the adaptive cruise control, as it has also caused issues while using it. It will often apply brakes if it detects a vehicle in another lane while driving, causing the vehicle to “slam” on the brakes going at high rates of speed (I.e. driving on the interstate at 80 mph) and has nearly caused accidents, as the vehicle becomes hard to control, and the risk of following vehicles not having the reaction time to avoid a rear-end collision is increased. My particular vehicle does not have an option to switch between regular cruise control, and adaptive cruise control. After talking with GM, they informed me the only way to “fix” the issue is to completely replace the module with an updated module that allows the option to turn off the adaptive cruise control, which is quite costly to the consumer. My vehicle is currently at a GM service department, and has been diagnosed that the brake pump has failed, and needs replaced. They are claiming that it is not covered under the recall. It is not covered under GM’s extended warranty due to mileage restrictions.

The contact owns a 2015 Chevrolet Suburban. The contact stated that the odor of fuel was present inside and outside the vehicle. The contact stated that upon investigation, it was discovered that fuel was leaking under the front of the vehicle. The vehicle was taken to the local mechanic who determined that the fuel line had ruptured due to excessive rubbing against other components. The fuel line was replaced, and the vehicle was repaired. The local dealer and manufacturer were notified of the failure, but no assistance was offered. The failure mileage was 155,000.

While traveling on the highway, my dashboard indicated that my transmission was overheating. I had to pull over immediately and turn off the engine to allow it to cool down in the middle of heavy traffic in an unsafe location almost getting hit my multiple vehicles at a high rate of speed. All regular maintenance has been done and it only has 119,000 miles. I purchased it in May 2023 with 113,000 miles from a reputable dealership and this occurred in October 2033, only 5 months later. There is a recall for this model and my vehicle is not included, which seems to be an ongoing issue with other consumers with the same year, make, and model. The transmission needs to be replaced and it’s costing over $6,000.

Periodically the steering goes away and makes the vehicle hard to maneuver and I also get some warning lights with it.

When I attempt to speed up or slow down my truck hesitates, and it's followed by a significant shake, like a shudder, and sometimes it just jerks, or clunks, like it's doing a very “hard shift” when the automatic transmission changes the gears. Sometimes it shifts so violently, I feel like I got hit by another vehicle. I've also tried to accelerate into traffic, and the truck hesitate and then abruptly and violently jerks into gear. It creates a big traffic safety issue! Other times the transmission shifts gears so hard that it slams the truck forward, and makes feels like I've been rear-ended. Now it barely shifts!
